Title: Improvements relating to flanging machines
Inventor: BOLDRINI RINO
IPC: B21D19/04
Filed: 1959-07-27
Abstract: 893,832. Flanging. BOLDRINI S.A. July 27, 1959, No. 25683/59. Class 83 (4). A flanging machine for metal sheets, for preparing flat or convex bottoms of tanks, boilers and containers and the like, of the kind wherein a pressing roll rotatable around its own axis acts with pressure on to the border of the metal sheet to make it adhere against another profiled shaping roll in such a manner that the metal sheet becomes shaped according to the profile of the latter roll, is characterized in that the pressing roll is supported by means combined in such a manner as to permit said roll to displace in two orthogonal directions, though leaving it free to rotate about its own axis. A tank bottom 4 to be flanged is clamped at its centre between pneumatic jack means 2, 3, adjustable along a frame 1, so that may be rotated about the axis X-X by means of a motor-driven shaping roll 5 against which the outer part of the bottom 4 is pressed by an idler roll 6 so that said outer part is formed with the profile of the roll 5. The roll 6 is carried on a stem 7 movable axially by hydraulic piston and cylinder means 8, 9. The cylinder 9 is movable vertically by hydraulic piston and cylinder means 19, 20, the cylinder 19 carrying the cylinder 9 on horizontal trunnions so that hydraulic piston and cylinder means 12, 13 connected to a support 15 on the stem 7 can pivot the cylinder 9 about a horizontal axis y-y. Thus the combination of the three movements imparted to the stem 7 and roll 6 by the cylinders 12, 9, 19 under control of hydraulic distributers causes the roll 6 to follow the profile of the shaping roll 5. Two idle pressing rolls 23 are provided to press up on to the sheet 4 by a pneumatic jack 25.

Title: Acceleration control for gas turbine engines
Inventor: LEWIS GEOFFREY ARTHUR
IPC: F02C9/32
Filed: 1960-07-25
Abstract: 954,638. Gas turbine plant. JOSEPH LUCAS (INDUSTRIES) Ltd. Aug. 25, 1961 [July 25, 1960], No. 25769/60. Heading F1G. [Also in Division G3] A gas turbine engine in which fuel is supplied to the burners by a pump 6 through conduits 8, 11 including a device 20 for producing a pressure drop dependent upon functions of the compressor outlet pressure acting on a diaphragm 14 and bellows 15 which actuate a lever 17 carrying a control valve 18 for the device 20 and connected by a spring 19 to the device 20 and in which the pressure drop across the device 20 is applied to a diaphragm 23 which operates a lever 26 to interrupt a conduit 27 and thereby reduce the stroke of the pump when a predetermined pressure drop across the device 20 is exceed so that stalling of the compressor is avoided during acceleration, has a pressure sensitive switch 36 which responds to the predetermined pressure drop to energize a solenoid 31 to open a control valve 30 and thereby cause opening of a compressor bleed valve 28. The latter action operates a switch 37 which causes closure of a valve 34 so that a smaller proportion of the pressure drop across the device 20 is applied to the diaphragm 23 and the predetermined pressure drop at which the acceleration control commences to operate is increased. This allows a greater degree of acceleration, which is permissible whilst the compressor bleed valve is open. In a modification, the electrically operated valve 34 is replaced by a valve operated mechanically by movement of the compressor bleed valve. In a further modification, the pressure sensitive switch is dispensed with, the actuator for the compressor bleed valve is sensitive to the pressure of the pump 6, and the lever 26 is acted upon by a spring having a mechanical coupling with the actuator for the compressor bleed valve.

Abstract: 529,566. Tobacco-stemming and like machines. INTERNATIONAL CIGAR MACHINERY CO. Sept. 18, 1939, No. 26077. Convention date, Oct. 22, 1938. [Class 130] For forwarding and transferring tobacco leaves, particularly for delivery to a stemming machine, a suction leaf conveyer 15 has an operative portion on which leaves are forwarded in succession, and a suction member 16 is periodically moved into close proximity to and parallel to the operative portion of the conveyer, and suction is cut off from the conveyer and applied at the same time to the suction member to transfer a leaf without disturbance. As shown, the leaves are advanced in succession, butt end first, along an upwardly inclined path by grippers 13 carried by a chain or chains 14, and pass through suction spreading compartments to a pair of endless perforated belts 15, on which they are held by suction in flat outspread condition. The belts 15 travel over suction chamber 18. At the position LC, the jaws of the gripper 13 are opened to release the stem butt. Beneath the belt 15 is a perforated belt 16 travelling over a suction box 17 pivotally connected at its lower end to a link 38 mounted on a crank pin 39 on a gear sector 40 meshing with a gear sector 42, which has an arm 44 connected by a rod 45 to a lever 46. Arms 47, 48 on the lever 45 are actuated by cams 51, 52 on a shaft 53 to move the suction box 17 towards and away from the belts 15. By means of valves 57, 63, actuated through linkage 58 ... 62 and 64 ... 68 from cams on the shaft 53, the transfer of a leaf from the belts 15 to the adjacent belt 16 is effected by cutting off suction from the chambers 18 and applying it to the box 17. From the position of transfer, the leaf advances tip-end foremost between belts 30, 31, and to prevent curling of the leaf tip, the advancing tip is held by an extension of one of the suction chambers S against a chain 32 and the belts 31 until gripped between the belts 30, 31. The leaf then passes to a stemming mechanism disposed beneath the shafts 36, 37.
